CHARLES Gr. TROSIEN, 0F PONTIAC, MICHIGAN.

GEAR-LOCK FOR AUTOMOBILES.

Application filed August 16, 1919.

To all Iwhom t may concern.'

Be it known that 1, CHARLES G. TuoslEN, a citizen of the United States, residing at Pontiac, county of Oakland, State of Michigan, have invented a certain new and useful Improvement in Gear-Locks for Automobiles, and declare the followingr to be a full, clear, and exact description of the Same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part ot' this specification.

My invention relates to gear. locks for automobiles and an object of my improvements is to provide an improved gear lock to be used with the construction ot' a Ford automobile.

ln the accompanying drawings:

Figure 1 is a plan view of thcphousing for the change speed gearing in a Ford automobile. f

Fig. 2 is a side elevation ot the same partly broken away. 7

F ig. 3 is a detail view of a part of the interior construction partly in section.

Fig. l is a detail inverted plan lview of the lower end of the locking cam rod.

Fig. 5 is a detail side elevation of the mechanism shown in Fig. 3 and adjacent part-s, partly broken away to show the interior construction.

Fig. G is a view similar to Fig. 5 the cam rod being 'in a diierent position.

Fig. 7 is a plan view of a portion of the housing, a modified form of construction embodying my invention being shown.

Fig. 8 is a section on the line VIII-VIII, Fig 7.

Fig. 9 is a View similar to Fig. 8 showing Vthe parts in a different position.

F ig. 10 is a detail section taken on the line X-X, Fig. 9.

Fig. 11 is an end View of the locking sleeve detached from the assembly.

Fig. 12 is a plan View of the casing with a. third modification of mechanism embodying my invention.

jacent i'aces of the locking sleeve and lug shown.

Fig. 1G is a modified construction of the form shown in Figs. 7 to l1, inclusive.

a is the housing for the change speed gearing, 7) is the transverse rock shaft, bearing in said housing and carrying the striker levers L2, b2. Upon the hubs ot' said levers extending upward l form adjacent lugs if", f'". c is a socket secured or formed in the cover of the casing a extending verti- -ally with its axis in the plane of the rock shaft 71, its lower end coming just above the lugs 7J, 1f. C2 is a cylindrical piece. or rod, having cams ci", c on its lower end. The "am rod c lits and is adapted to rotate'in the lower end of the socket c and extends downward therefrom so that its cams c3, c3 come in the plane oi the lugs 71?. 713. Then the rod C'- is turned to the position shown in Fig. 5 the cams c3. c3 come in the line ot' travel of the lugs 7), 71"" and the rod 7) is therefore locked and restrained from turning. 'hen the cam rod c2 is turned at right angles to the position shown in'Fig. that is, to the position indicated in Fig. G, the lugs c come at the side of the lugs b3 and are not in the line ot travel of the latter so that the rod Y) is 4free to turn or rock in its bearing. c4 is a spindle extending upward from the cam rod c2 and connected at its end with the barrel of a pin-lock ci' which may be operated by a key c6.

In the form shown in Figs. 7 to 11, in- I pinned or vkeyed upon the shaft with its aceA adjacent to a corresponding face formed at 53a is an aperture formed in the` face of the sleeve 52a so that when the rock shaft is in its normal position said aperture shall be axially in line with the aperture 6 with the socket piece ca. e is a ball in the apertures c, 63a. `lVhen the rock shaft b is unlocked, as shown in Fig. 9 the cam rod c2 is turned to the position shown in the last-named figure, so that the ball e is free to more entirely into the aperture in the socket piece 0a, and the sleeve 52a, Will turn freely. When the cam rod 02 is turned to the position shown in Fig. 8, the cam 03a thrusts the ball e partly out of the aperture e so that it shall engage in both of the apertures 63a and c so that the sleeve 52a and consequently the rod b is locked to prevent a rocking motion.

Instead of the arrangement just described in Which the ball e engages in two cavities, one of which is in a stationary part and the other located eccentrically in a part connected to the rod b, a vertically reciprocating rod 02a (Fig. 16) may be used, which, at the lower end of its travel engages in two apertures baaz and 06a, one of which is stationary and the other eccentrically located in the rod b.

In the forms shown in Figs. 12 to l5 inclusive, there is a sleeve g keyed upon the shaft Z) so as to restrain it from relative angular motion but permitting of motion longitudinally of the shaft b. This is provided with a transverse slot g2 at its upper i. artion and with two lugs gi at opposite points of its periphery. There is a lug f' formed opposite the sleeve g upon the wall of the casing a and in this lug are formed slots or apertures f2 corresponding to the lug g3 0n the sleeve g. There is a cam rod c2 having an eccentric lug 03a thereon which engages in the slot g2. When the rod c2 is turned to one position the sleeve g is moved by a compression spring L to its position farthest to the left, as shown in Fig. 15, and the lugs g3 are entirely clear of the slots f2. When the rod 02 is turned the cani 03a engages a wall on the slot g2 forcing the sleeve g to the right and engaging the lugs g3 in the slots and the rock shaft b is locked from angular motion.

What I claim is:

1. In an apparatus of the kind described, a transmission gear casing, a transmission gearing in said casing, a roclc shaft inolosed in said casingv and forming a part of the transmission gearing, a part adjustable at will extending through said casing and adapted to engage said rock shaft and disengage the same and means for locking said part in its/'engaged position.

2.' In an apparatus of the kind described', a transmission gear casing, a transmission gearing in said casingga rock shaft inclos'ed in said casing and forming a part of the transmission gearing, a movable part engaging a stationary support, and means -adjustable at Will extending through said a stationary part provided with aslot axially in line with the first-mentioned slot,

a part adapted to reciprocate in said slot and a rod extending throughV said casing adapted to actuate said reciprocating part to cause it to engagej'in both of said slots or to engage solely iiyne of said slots and a lock for preventing `the movement of said rod.

4. In an apparatus of the kind described, a transmission gear casing, a transmission gearing in said casing, a rock shaft inclosed in saidcasing and forming a part of the tran'sinis'sion gearing, a sleeve upon said rod rig,Y s4 cured thereto, said sleeve being providedfivith an aperture in its side face, a statiiliaryl part provided with an aperture 'in'lin'envith and forming anfextensionroffth t'mentioned aperture, aball :eciprocatellin/ said apertures,

j j y dapted Vactiiate said ball for the purpose descri ,.nd'fmeans 'for locking said rotatableri'od.

In testimony Whereofl I sign this specification.
